Grain Sorghum Varieties

Grain sorghum is the most common type, primarily cultivated for its edible grains, used in human food and animal feed. These varieties are selected for high yields, good grain quality, and resistance to pests and diseases. Some popular grain sorghum varieties include:

  • Hybrid Sorghum: These are bred for higher yields and improved traits.
  • Open-Pollinated Sorghum: These can be saved and replanted, offering cost savings but potentially lower yields.

When selecting grain sorghum, consider its maturity time, which ranges from early-maturing (70-80 days) to late-maturing (120+ days). Also, consider the grain’s color, which can vary from white to red or brown.

Forage Sorghum Varieties

Forage sorghum is grown primarily for animal feed. These varieties are often taller and leafier than grain sorghum, producing a larger biomass. They are often used as silage or hay for livestock. Common forage sorghum varieties include:

  • Sorghum-Sudangrass Hybrids: These hybrids offer fast growth and good forage quality.
  • Sudangrass: Known for its rapid regrowth after cutting.

Forage sorghum selection depends on the livestock you are feeding, as different varieties have varied nutritional profiles. Consider yield potential, palatability, and prussic acid levels (which can be toxic if not managed properly).

Sweet Sorghum Varieties

Sweet sorghum is grown primarily for its sweet stalks, which are used to produce sorghum syrup. These varieties have high sugar content in their stems. They require specific processing to extract the syrup. Sweet sorghum varieties include:

  • Sugar Drip: A popular choice for syrup production.
  • Rox Orange: Another widely grown variety known for its high sugar content.

When selecting sweet sorghum, consider the sugar content and stalk yield. Ensure you have the necessary equipment for juice extraction and syrup processing.

Seed Quality and Certification

Always purchase certified seeds from reputable suppliers. Certified seeds have been tested for germination rates, purity, and disease resistance. This ensures that you are starting with high-quality seeds, which can significantly impact your crop’s success. Always check the seed’s expiration date, as seeds have a limited shelf life.

Inspect the seeds for any signs of damage or disease before planting. Seeds should be clean, uniform in size, and free from pests. Poor-quality seeds can lead to uneven germination and reduced yields. Investing in quality seeds is an essential part of learning how to plant sorghum seeds.

Preparing the Soil for Planting Sorghum Seeds

Proper soil preparation is crucial for sorghum growth. Sorghum thrives in well-drained soil with a pH between 6.0 and 7.5. Soil testing is highly recommended to determine the soil’s nutrient levels and pH. This information will help you amend the soil with the appropriate fertilizers and amendments.

Sorghum is relatively tolerant of various soil types but prefers loamy soils. These soils provide good drainage and aeration, which are essential for healthy root development. Heavy clay soils can be problematic, as they can become waterlogged and hinder root growth. Understanding your soil type is critical to knowing how to plant sorghum seeds successfully.

Soil Testing and Amendments

Before planting, conduct a soil test to determine the nutrient levels (nitrogen, phosphorus, and potassium) and pH. The soil test results will provide specific recommendations for fertilizer application. Soil testing helps prevent over-fertilization, which can damage the environment and waste resources. Contact your local agricultural extension office for soil testing services.

Based on the soil test results, amend the soil as needed. If the soil is deficient in nutrients, apply the recommended fertilizers. If the soil pH is too low (acidic), add lime to increase the pH. Incorporate organic matter, such as compost or well-rotted manure, to improve soil structure, drainage, and water retention. Organic matter also provides essential nutrients for the plants.

Planting Depth and Spacing

The optimal planting depth for sorghum seeds is 1-2 inches. Planting too shallow can result in poor germination if the soil surface dries out. Planting too deep can hinder the emergence of seedlings. Use a planting depth gauge on your planter to ensure consistent depth.

The spacing between plants depends on the variety of sorghum and the intended use. For grain sorghum, a common spacing is 4-8 inches within rows, with rows spaced 24-36 inches apart. For forage sorghum, wider spacing may be used to promote larger plants. Follow the specific recommendations for your chosen variety.

Planting Time and Conditions

The best time to plant sorghum is when the soil temperature consistently reaches 65-70°F (18-21°C). This typically occurs several weeks after the last frost. Planting too early can lead to slow germination and seedling damage from cold temperatures. Planting too late can shorten the growing season and reduce yields.

Sorghum requires adequate moisture for germination and early growth. Plant when sufficient soil moisture is present, or be prepared to irrigate if rainfall is insufficient. Monitor weather forecasts and plan planting around predicted rainfall patterns. Optimal timing and conditions are essential when learning how to plant sorghum seeds.

Planting Methods: Row Planting vs. Broadcasting

Row Planting: This involves planting seeds in rows using a row crop planter or drill. This method allows for precise seed placement, uniform plant spacing, and easier weed control. Row planting is generally preferred for grain sorghum and for larger-scale operations.

Broadcasting: This involves spreading seeds evenly over the soil surface. This method is often used for forage sorghum or in smaller gardens. Broadcasting requires more seed and can make weed control more difficult. After broadcasting, lightly incorporate the seeds into the soil by harrowing or raking.

Seed Rate Calculation

The seed rate is the amount of seed required per acre or other unit of area. The seed rate depends on the variety of sorghum, the desired plant population, and the germination rate of the seeds. A higher seeding rate can be used if you want to compensate for lower germination rates or anticipate some loss due to pests or diseases.

To calculate the seed rate, consider the following factors:

  1. Desired Plant Population: The number of plants you want per unit of area.
  2. Seed Germination Rate: The percentage of seeds that are expected to germinate (printed on the seed packet).
  3. Seed Purity: The percentage of the seed packet that is the sorghum seed (also on the packet).
  4. Seed Weight: The weight of 1000 seeds (also known as the thousand kernel weight or TKW).

Use these factors to calculate the seed rate per acre or other unit of area. Consult with your local agricultural extension service for specific recommendations on seed rates for your region and variety.
